SEPARATOR FOR RING-SPINNING FRAMES.

SPECIFICATION forming part of Letters Patent No. 459,894, datedSeptember 22, 1891.

Application filed February 6, 1891. Serial No. 380,492. (No model.)

To all whom it may concern:

Be it known that I, DANIEL J. GREEN, of Fall River, county of Bristol,State of Massachusetts, have invented an Improvement in Separators forRing Spinning Frames, of which the following description, in connectionwith the accompanying drawings, is a specification, like letters on thedrawings representing like parts.

Ring-spinning frames are now commonly provided with separators or bladesto stand between adjacent bobbins or spindles above the ring-rail, andvarious means have been employed for actuating these separators. Theseparators, as herein shown, are connected to a carryingbar of usualconstruction, it having-suitable pivots, the bar having co-operatingwith it suitable backwardlyextended arms, upon which are mountedadjustable counterbalancing-weights, which nearly but not entirelycounterbalance the weight of the separator-blades which are extendedacross the ring-rail, the latter in its upward movement striking theseparator-blades and elevating them.

This invention has for its object to provide means whereby theseparator-blades may be readily lifted whenever the bobbins are to bedoffed, the ring-rail at such time being well down. In accordance withmy invention, therefore, I have joined the bar carrying theseparator-blades with the usual guide-board by means of a connection,(herein shown as a chain,) so that when the guide-board is lifted itwill automatically lift, through the connection, the separator-blades.

Figure 1 in partial section shows a suflicient portion of aring-spinning frame to enable my invention to be understood. Fig. 2 is apartial front elevation thereof, and Fig. 3 a section in the line 00.

The frame-work A, the rail A, upon which rests the usualspindle-supports B for the usual sleeve-whirl spindles 0, having bobbinsD, and the separator-blades E on rods ace, forming the carrier-bar, towhich the said blades are secured by screws a, the backwardly-extendedears I), having pivots to rest in bearings on the stands 1), dependingfrom the roller-beam (Z, the arms 6, shown as connected to the ears b,and the cou nterbalancingweights f, the hinged guide-board g, and thestand or are and may be all substantially as common in ring-spinningframes. In accordance with my invention I have added to these old andwell-known parts a connection h, shown as a chain, the upper end ofwhich is joined with the guide-board the junction in this instance beingshown as made by a hook it, the lower end of the said connection beingin turn attached to the separator-carrier bar, or it may be to aseparator of whatever construction, the attachment, as represented,being made by a hook, which, after the connection has been passed fromabove under the lower rod a, is hooked over the upper rod a, as shownbest in full lines in Figs. 1 and 2.

When the bobbins are to be doffed,the op erator, by engaging thehand-piece m on the guide-board, lifts the said guide-board into thedotted-line position, Fig.1, until the hook m, pivoted upon theroller-stand m engages a projection m which hook thus acts to hold upthe guide-board. Lifting the guide-board as represented also lifts therod to which the separators are attached, placing the said separators inthe dotted-line position, Fig. 1, so that the bobbins may be doffedwithout interfering with the separators. The lowering of the guide-boardenables the separators, which are slightly heavier than thecounterbalancing-weights, (one ormore of which may be used, according tonumber of separatorblades,) to fall into working position.

I claim 1. In a ring-spinning frame, a ring-rail, a series of spindles,a pivoted or hinged guideboard, and a separator-carrying bar providedwith a series of separators, the said bar being located below theguide-board, combined with connections whereby the lifting of theguideboard automatically effects the lifting of the separatorspreparatory to doffing, substantially as set forth.

2. In a ring-spinning frame, a spindle, a ring-rail, a counterbalancedseparator-carrying bar located between the ring-rail and the tops of thespindle or bobbin carried thereby, and a series of separators, combinedwith a hinged or pivoted guide-board and with a connecting devicebetween the said guide-bar and the separators, whereby the lifting ofthe guide-board lifts the separators and places them in position fordoifing, substantialiy as described.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

DANIEL J. GREEN.
